Banana mosaic virus is considered a viral disease that leads to leaf deformities and reduces plant productivity. In this article from “WORLD OF PLANTS,” we review how to identify this disease and ways to combat it.
Introduction to banana mosaic virus
Banana mosaic virus BANANA MOSAIC VIRUS
المرادفات: Banana infectious chlorosis virus
The virus that causes this disease is the cucumber mosaic virus. The virus has many strains that infect many dicotyledonous and monocot plants, the latter of which is the banana plant, which it infects in most of its growing areas in the world. The resulting disease is given many names, such as banana mosaic. banana mosaic, metallic yellowing in bananas, banana infectious chlorosis, and banana heart rot. Banana infection with this virus was recorded in Egypt in 1953.
Transmission of banana mosaic virus
The virus is transmitted experimentally through infection with gastric juice, and is also transmitted through planting infected banana cuttings.
Aphids transmit this virus, and the strain of the virus that infects bananas is carried by several aphids that transmit the original virus. The insects that transmit this virus cannot transmit the banana mosaic virus, and the aphid Pentalonia nigronerosa, which transmits the mosaic virus, cannot transmit the cucumber mosaic virus.
Symptoms of banana mosaic virus
Symptoms vary depending on the affected variety and the prevailing environmental factors. In general, infected plants are weak, with leaves somewhat smaller in size than healthy plants. The leaves may tend to yellow or be characterized by the presence of scattered yellow areas with greener areas. This may have only a cycle or yellow lines or bands alternating with the green color. of the leaf and extending from the central vein to the edges. The leaves appear curled at the edges, their unfolding rate decreases, they are fragile and easily torn, and their petioles are dotted with pale dots. They often consist only of necrotic lines on originals and false contexts. As a result of the small leaf blades and petioles, it may show an appearance similar to the blotting that characterizes banana leaf blotting disease. The infected plant bears less fruit.
Yellowing of leaves may be accompanied by heart leaf rot, depending on the prevailing environmental conditions. In this case, the rot extends from the top to the bottom.
Infection of young plants leads to stunting of the plants and they may die and the infected leaves may fall. In advanced stages of the disease, the calves may die.
Resistance to banana mosaic virus
Use healthy seedlings in cultivation. Banana plantations must also be visited constantly and infected plants should be uprooted and destroyed. It is also recommended to resist vector insects and weeds and not to plant vegetables next to or inside banana plantations.
Cause of banana mosaic virus
Crown rot is a fungus (Phytophthora cactorum) that can survive in the soil for years. Swimming germs depend on free water to spread, and are also spread by spraying water. Waterlogging is a common source of root rot fungus infection.
Preventive measures for banana mosaic virus
- Planting in well-drained areas.
- Avoid overwatering.
- Avoid direct contact with soil of leaves or fruits.
- Use wood wool or straw as the underlayment.
- Do not plant in contaminated areas.
- Use resistant varieties
Organic control of banana mosaic virus
There is no direct treatment and it is possible to apply preventive measures to avoid infection.
Chemical control of banana mosaic virus
An integrated preventive measures approach should always be considered together with biological resistance if available. You can add mefenoxam and metalaxil to drip irrigation water in contaminated areas to prevent outbreaks.
